The physical mechanism for vortex merging
C Cerretelli, CHK Williamson - Journal of Fluid Mechanics, 2003 - cambridge.org
In this paper, we study the interaction of two co-rotating trailing vortices. It is well-known that
vortices of like-sign ultimately merge to form a single vortex, and there has been much work …
